REFERENCE-STAKE I PPRQTECTOR.

Specification of Letters Patent. Patented D 28 .1920

Application filed November 17, 1919. Serial No. 338,748.

To all whom it may concern:

Be it known that I JOHN T. WELDoN, a citizen of the United States, and resident of Milwaukee, in the county of Milwaukee and State of lVisconsin, have invented certain I new and useful Improvements in Reference- Stake Protectors; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention pertains to new and useful improvements in protectors, and has special reference to devices for covering and shielding reference stakes such as those used for landmarks or by surveyors.

It is well known that stakes of this nature, particularly when they are of wood, are readily mutilated and displaced compara tively easily, and as a result much unnecessary labor and time is spent in replacing or re-locating the same. The object of the invention is, therefore, to provide a simply constructed means by which the stake or other marker may be housed and protected.

Inasmuch as these reference stakes frequently bear a legend, or at least some distinguishing characteristic on their tops, pro vision is made in the protector for viewing the stake without removing the former.

For the purpose of adding strength to the protector and to also more effectively shield the stake or the like, the same is made domeshaped; any object will thus be deflected from the center of the protector toward its outer edge.

lVith these objects in view, and others which will become apparent as the description proceeds, the invention resides in certain novel features of construction and arrangement of parts which will be hereinafter described and claimed.

In the accompanying drawing:

Figure 1 represents a plan view of a protector constructed in accordance with my invention, and

Fig. 2 is a vertical diametrical sectional view taken approximately on the plane of the line 2-2 of Fig. 1.

Referring more particularly to the drawing wherein similar reference characters designate like parts in each of the views, it will be seen that the character S denotes a surveyors stake of ordinary design which is adapted to be driven into the ground in such a manner as'to permit a portion to project thereabove, this portion ordinarily bearing a legend or the like (not shown in the present instance). Over this projecting end of the stake is placed the invention which consists of a protecting member in the form of a circular dome-shaped shield l, the same preferably consisting of a concavo-convex casting, the center of which is spaced slightly above the top of the stake S as the same is normally driven into the ground. The outer or peripheral edge of the shield 1s provided with a laterally extending annular flange 2 which forms a seat'for engagement with the ground. The center of the shield has a circular sight opening 3 through which the stake S may be viewed.

For the purpose of securing the shield in position soas to center the stake S with the sight opening 3, and to prevent ready removal of the same, said flange 2 has a plurality, preferably three, depending ground engaging pins 4. The flange 2 immediately above each of the pins at is provided with impact receiving and reinforcing bosses 5. From the drawing it will be seen that these bosses in addition to overlying the tops of the pins extend up the side wall of the shield a certain extent, and since all of these several parts, that is to say the shield 1, the

flange 2, the pins 4, and the bosses 5 are cast integrally, the latter will effectively brace said flange at a plurality of points. In

addition the bosses are adapted to receivethe blows of a hammer or the like should it be necessary to drive the pins 4 into the ground. Ordinarily the pins may be pressed into the ground by the engagement of a persons foot with the flange 2 or with the bosses 5.

As hereinbefore mentioned a dome-shaped shield will tend to deflect objects from the center of the same, and for this reason it is not necessary that the protector be of such heavy material as would be the case if it was of a different shape. Regardless of this fact, however, it is to be understood that the invention is not limited to the particular protector illustrated, and that various changes may be made in proportion and location of parts as well as in the form thereof.

I claim:

1. A. removable protector for surveyors reference stakes comprising a cover member having a laterally extending ground engaging flange projecting from its edge, said member being seated over a stake with said flange in contact with the ground, and means carried by the member for detachable engagement in theground to prevent the said member from shif ing with respect to the stake.

2. A removable protector for surveyors reference stakes comprising a cover member having a laterally extending ground engag ing flange projecting from its edge, said member being seated over a stake with said flange in contact with the ground, said member being domed to strengthen the same and to deflect objects therefrom, and means carried by the member for detachable engagement in the ground to prevent the said ment her from shifting with respect to the stake.

3. A removable protector for surveyors reference stakes comprising a cover member having a substantially central sight opening, the member being adapted to be seated on the ground over a stake with the latter below and visible through said sight opening, and means for holding the member against shift ing with respect to the stake and to prevent disalinement of the sight opening therewith.

4. A removable protector for surveyors reference stakes comprising a cover member having a substantially central sight opening, said member being domed to strengthen the same and to deflect objects away from the sight opening, a laterally extending ground engaging flange projecting from the edge of said member, and retaining pins depending from said flange, said member being adapted to be seated over a stake with the flange in contact with the ground and the pins in removable engagement therewith, the stake being below and visible through said sight opening.

In testimony that I claim the foregoing I have hereunto set my hand at Milwaukee, in the county of Milwaukee and State of Wisconsin.

JOHN T. VVELDON
